Ideal Core for 337k tracks?

That sounds about right for 24,000 CDs ripped to flac: 8.4TB / 350MB = 24,000.

I would turn the question around, how can you need 8+ TB for 78k tracks?
I have 39k tracks, most CD quality FLAC, and it’s only 1.25 TB.

He must have a heck of a lot of 24/192 files. Otherwise, it makes no sense.

I have 6400 cd’s, 950 of which are DSD,all totaling 6.4TB of storage

I tell people an average of 3000 CDs per 1TB. That assuming 10 tracks per CD and most CDs are not the full 60 minutes. Our CD ripper uses standard FLAC (lossless) compression at 2 to 1.

So 30k tracks per TB.
15K per TB is you have AIFF or WAV (no compression)
150K per TB for mp3. mp3 is about 10 to 1 compression.

And a lot less if you are using DSD, hi-rez or other hi bitrate formats.

That accounts for the difference since these files are an order of magnitude larger; approx 4TB of your collection.

Thanks guys

I lost track of how many DSD files I have…

I’m serving a larger library via a dedicated Asus Mini ITX with i5-7600T CPU running Arch Linux and apart from the Genre browse (which I suspect has never been optimised by the dev team) Roon is pretty much instantaneous on my iPhone, Pixel 2 and a Win 10 client I set up over the weekend for testing. Once the library scanning is done the only things that matter (I don’t upsample) are sufficient ram, ram speed, local storage and the fastest SSD you can get your hands on. The entire thing is set and forget, it just works…no need to buy some 3rd party branded device that’s pretty much going to do the same thing at a premium unless you want it sitting in or on your hi-fi rack. My Roon server is nowhere near my listening environment.

Ditto my library is a bit smaller, 120k files

I have i7 7700 16 g ram, 250 ssd ,4 tb spinning drive

All generic stuff

FYI - here’s a previous discussion of having a huge library:
https://community.roonlabs.com/t/my-experiences-with-rock-and-a-500k-tracks-library/27385/10?u=wklie

Very interesting thread! But unfortunately it leaves me confused. It says that for collections greater than 300K tracks you should really use Windows. Does that rule out Nucleus+? Is there a pre-built Windows-based server that anyone would recommend?

we’ve made some optimizations since that time, and 500k is still radically different than 337k.

Thanks, Danny. That’s great news and I would much prefer to go the Nucleus+ route. But I will point out that in that thread Brian (Roon CTO) said the following (note the reference to libraries with 300K+ tracks):

That was the advice before Nucleus existed. It was a proven solution but as Danny says, there have been optimisations to Roon and there continues to be improvements in areas in Linux where previously Windows 10 was unquestionably superior. What does @danny think about the possibility of getting Nucleus to work in clusters? So for those really big libraries you got 2 to load share?

@Steve_Fisher – updated his post w/ an edit at the top.

I think that is a large amount of work for the handful people with libraries larger than 1m tracks. Until that point, you can still buy powerful enough single devices.

Dear @Steve_Fisher,

Thank you for choosing QNAP NAS, and we would like to help you on the Roon and NAS issues. Would you please submit a ticket via QNAP Helpdesk and kindly provide us your ticket number? Our support team will contact you in time, thank you very much!

Nice of QNAP marketing to chime in here… :smiley:

Steve,
Although I am sure a Nucleus+ would be better (I’m waiting to try one), the configuration you are describing is almost exactly the same as one I have been running for a while. I use the same Qnap for 350k tracks and since it settled down (which took a few weeks of analysis etc) it has been very reliable. I don’t have need to reboot Qnap (current uptime 101 days).
Having said that, it depends I imagine on what else you are asking it to do. Although I use several endpoints, I never request signal processing on the Qnap - I suspect that would stress it out.
My interest in the Nucleus+ is faster focussing.
The image below shows the resource usage on Qnap.

I was prompted to answer you about the Ultradac. In my experience the Sooloos network endpoints will always give a better sound than a USB connection, especially from a PC or Qnap. At this level of performance everything makes a difference, including cables, router etc.
Danny is right that having the analogue audio parts well away from ‘radio noisy’ networking is a good idea.
